(3ab)×(4ab-4)

3ab×(4ab-4)

12a²b²-12ab

Answer 2

To simplify the expression (1,5a2b) · (4ab-4), we can use the distributive property of multiplication over addition/subtraction.

First, let's distribute 1,5a2b to both terms inside the parentheses:

(1,5a2b) · 4ab - (1,5a2b) · 4

Multiplying each term separately:

(1 · 4ab) + (5a2b · 4ab) - (1 · 4) - (5a2b · 4)

Simplifying further:

4ab + 20a²b² - 4 - 20a²b

Combining like terms:

20a²b² - 20a²b + 4ab - 4

So the simplified expression is 20a²b² - 20a²b + 4ab - 4.
